SwipedOn is a simple iPad app built to solve one problem. In an emergency, would you know who is at your workplace?
Employees, visitors and contractors register on/off the iPad.
In the event of an emergency, the iPad is picked up and everybody is checked off on the iPad (or direct printed list).
It is currently used in offices, factories, construction/engineering sites, boarding schools and even superyachts around the world.
Simple concept, beautiful solution.
